Definitions

  • the present disclosure relates to an attachment assembly for attaching a second object to a first object, the attachment assembly comprising a fastening member and a washer.
  • the attachment assembly may further comprise a bushing.
  • the disclosure further relates to a use of the attachment assembly for attaching an inflatable curtain to a vehicle, to a cantrail and to a vehicle, as well as a method for attaching a second object to a first object.
  • Attaching a second object to a first object may sometimes be difficult for one person, since there is a desire to simultaneously hold the second object at a suitable position for fastening, to hold a fastening member, such as a screw, and to hold a tool used for attaching the fastening member, such as a screw-driver.
  • the difficulties are increased if the second object is large and/or heavy. It is also more difficult if there is limited space available for the person doing the work and/or the person cannot see the position of the attachment.
  • a typical situation may be when attaching an object, such as a panel, to a wall or a ceiling of a building, e.g. during construction.
  • Another typical situation is during assembly of a vehicle when attaching an automotive part to the vehicle, e.g. when attaching an inflatable curtain to a cantrail, i.e. the portion of a vehicle body extending between the A, B and/or C pillars at the upper part of the vehicle.
  • the inflatable curtain is an airbag, which is adapted to cover the upper part of a vehicle's side in case of a side impact collision, thereby cushioning the heads of the passengers seated at that side. Since the inflatable curtain is part of a passenger protection system, it is desired that the fastening member is secured by a predetermined torque.
  • Such attachment work may more easily be done by two persons, e.g. one person holding the second object in position and the other fastening it by means of the fastening member using the tool.
  • Prior art solutions making it possible for one person to attach one object to another include using a temporary fixation of the second object to the first object, e.g. by means of a clamp to the first object or by a stand standing on e.g. the floor and pressing the second object towards the first object. Time is then spent to arrange the temporary fixation and to remove it afterwards.
  • Document US 6,851,710 B2 discloses using a clip, which is pushed into a corresponding opening of the vehicle surface thereby attaching an inflatable curtain to a vehicle.
  • a clip is used in combination with a rigid mechanical fastener, illustrated as a bolt.
  • the object of the present disclosure is to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
  • an attachment assembly for attaching a second object to a first object, the attachment assembly comprising
  • the first object may be a wall or a ceiling of a building.
  • the first object may a body of a vehicle, e.g. a cantrail or an A, B or C pillar.
  • the second object is typically large and/or heavy, such that it is difficult to handle for one person.
  • the second object may be a panel, e.g. a wall or ceiling panel.
  • the second object may be a panel or an inflatable curtain.
  • the fastening member is preferably a screw having a thread, but also other fastening members, such as a bolt and nut connection or a nail, would be possible.
  • the screw is intended to be screwed into the first object to thereby attach the second object to the first object.
  • a screw is an externally threaded fastener capable of being inserted into holes in assembled parts, or mating with a preformed internal thread or forming its own thread, and of being tightened or released by torqueing a head of the screw.
  • the washer may be welded or glued to the first object or fixated to it in some other way known by the skilled person.
  • the expression washer as used herein is intended to mean a flat, thin ring or plate of any shape.
  • the fastening member e.g. the screw, and the washer are manufactured separately from each other. They may also be sold and/or used as separate units, being prepared for later attachment to each other.
  • the washer may be delivered as a part of the first object, e.g. a cantrail being sent to an assembly plant for vehicles, wherein another automotive part, such as an inflatable curtain, is attached to the cantrail.
  • the fastening member e.g. the screw, may be delivered as a separate unit or may be comprised in the automotive part.
  • the second object is provided with a hole, having a large enough diameter for the shaft of the screw to pass.
  • the head of the screw has a larger diameter than the shaft, such that the screw is able to retain the second object in place.
  • a washer may be used adjacent to the head of the screw for retaining the second object.
  • One, two, three or more resilient members may be used in the attachment assembly.
  • the fastening member is a screw and the resilient member is arranged in the opening of the washer such that, by applying an axial force to the screw, the resilient member is displaced from the first position to the second position by the screw, thereby allowing the screw to be pushed through the opening by means of the applied force, and when no such force is applied, the resilient member assumes the first position, thereby retaining the screw.
  • the screw is thus passed through the opening of the washer by being pushed.
  • the resiliency of the resilient member is selected such that hand force is enough.
  • the screw may pass through the opening also if the force deviates from axial, as long as it has a component in the axial direction of the attachment assembly.
  • the resilient member may be arranged to define an inner diameter of the opening of the washer.
  • the inner diameter of the opening is less than an outer thread diameter of the screw and larger than an inner thread diameter of the screw.
  • the inner diameter of the opening is larger than the outer thread diameter of the screw.
  • the resilient member may comprise at least one flap protruding into the opening of the washer, the flap being in the plane of the washer, when in the first position of the resilient member, and a portion of the flap being displaced to a position out of the plane of the washer, when in the second position of the resilient member.
  • the flap may be moved from the first to the second position by the screw being pushed through the opening of the washer.
  • the attachment assembly may further comprise a bushing, which is fixedly attachable to the first object, the washer being fixedly attachable via the bushing to the first object.
  • the bushing may be welded or glued to the first object, e.g. a cantrail.
  • the cantrail may in such a case be delivered comprising the bushing and the washer to an assembly plant for vehicles.
  • the bushing may comprise a receptacle for receiving the screw.
  • the receptacle of the bushing may be a through-going axial bore.
  • the receptacle may also be a hole in the bushing or a hole in the first object.
  • the receptacle may comprise a portion forming a seat for the washer. This portion may have a larger diameter than the main portion of the receptacle, since the diameter of the main portion is adapted to provide a good attachment for the screw.
  • the screw is a thread-cutting screw. It may then cut its own thread in the receptacle.
  • the thread-cutting screw provides a higher friction than a corresponding non-thread-cutting screw, thereby increasing the mechanical strength of the attachment. It is thus possible to use a screw of smaller dimensions, e.g. by going down one step in the ISO metric M series of screw dimensions.
  • using a thread-cutting screw reduces the risk that the attachment assembly is destroyed due to improper alignment of the threads of the screw and the receptacle, respectively. There will thus be a higher tolerance for tightening the screw with a slightly oblique angle.
  • the inner diameter of the receptacle is preferably less than the outer thread diameter of the screw, such that the screw will cut into the inner wall of the receptacle. If the receptacle comprises portions having different diameters, e.g. due to that there is a seat for the washer, it is the main portion of the receptacle, which has the inner diameter of the receptacle being less than the outer thread diameter of the screw.
  • the screw may be adapted to cut its way through the material of the first object.
  • the first object may then, or may not, be provided with a receptacle.
  • a suitable material for the screw is steel.
  • a suitable material for the washer is plastic.
  • a suitable material for the bushing is steel. If the screw is thread-cutting, the material characteristics of the bushing are selected such that the screw is able to cut threads in the bushing.
  • an attachment assembly as described above for attaching an automotive part to a vehicle, wherein the first object is a body of the vehicle, e.g. a cantrail, and the second object is an automotive part, e.g. an inflatable curtain.
  • a cantrail for a vehicle comprising the washer of the above-mentioned attachment assembly. If the above-mentioned bushing is used, the cantrail may also comprise the bushing.
  • a vehicle comprising the above-mentioned attachment and an inflatable curtain being attached to a body of the vehicle by the attachment assembly.
  • a method for attaching a second object to a first object by means of an attachment assembly comprising a fastening member adapted to be attached to the first object, and a washer comprising an opening for receiving the fastening member.
  • the washer is fixedly attached to the first object, and comprises a resilient member located at the opening, which resilient member is displaceable between a first position, wherein the resilient member retains the fastening member, and a second position allowing passage of the fastening member through the opening.
  • the first object is a body of a vehicle, e.g. a cantrail
  • the second object is an automotive part, such as an inflatable curtain
  • the fastening member is a screw. The fastening is then carried out by screwing.
  • Figure 1 schematically illustrates a side view of a portion of a vehicle 1 comprising an inflatable curtain 3.
  • the inflatable curtain 3 is shown in its deployed state, wherein it is ready to protect a passenger at a side impact on the vehicle 1.
  • the inflatable curtain 3 is attached to a body of the vehicle 1, e.g. to a cantrail 5.
  • the inflatable curtain is in a storage state, see Figure 2 , wherein it is folded and or rolled to a tubular shape.
  • An inflator 7 is connected to the inflatable curtain.
  • the inflator 7 may be activated by crash sensors, in case a collision occurs, thereby inflating the inflatable curtain 3, such that it assumes the deployed state as illustrated by Figure 1 .
  • the inflatable curtain 3 is attached to the cantrail 5 by means of brackets 9.
  • the bracket 9 is used to retain the inflatable curtain 3 to the cantrail 5.
  • a portion 11 of the bracket 9 at least partly encircles the tubular shape of the inflatable curtain 3.
  • the encircling portion 11 may be resilient and comprise a slot (not illustrated). When the encircling portion 11 is to be connected to the inflatable curtain 3, the slot is widened such that the inflatable curtain 3 can be entered through the slot and then the encircling portion 11 springs back to a retaining position, as the one illustrated in Figure 2 .
  • the bracket may be clipped to or around the inflatable curtain 3, or the bracket may be glued or welded to the inflatable curtain 3.
  • the bracket 9 comprises a hole 13 suitable for a screw 15.
  • the hole 13 has a diameter, which is large enough for the screw 15 to go through, but which is small enough for a head 17 of the screw 15 to be stopped, such that the head 17 will be able to retain the inflatable curtain 3, once the screw 15 has been attached to the body of the vehicle, e.g. the cantrail 5.
  • the head 17 has a larger diameter than the rest of the screw 11.
  • a washer may be used to further increase the diameter of the head.
  • Figures 3-5 illustrate an attachment assembly 19 according to a first embodiment of the invention.
  • the attachment assembly 19 of the first embodiment comprises a bushing 21, a washer 23 and the screw 15.
  • the attachment assembly 19 has an axial direction, denoted by A in the Figures 3-5 .
  • Figure 3 and 4 illustrate the bushing 21 and the washer 23 without the screw 15 being inserted.
  • the attachment assembly 19 may be used for attaching the inflatable curtain 3 to the cantrail 5, see Figures 1 and 2 .
  • the bushing 21 is preferably embedded in the cantrail 5, such that the bushing 21, and thereby the washer 23, is fixedly attached to the cantrail 5.
  • the bushing 21 may for example be welded to the cantrail 5.
  • the bushing 21 comprises a receptacle for the screw 15 in the form of a through-going axial bore 25 comprising a main portion 26 having a diameter d r .
  • the receptacle further comprises a portion forming a seat 27 for the washer 23.
  • the diameter of the seat 27 is about as large as the outer diameter of the washer 23.
  • the washer 23 may be placed into its desired position in the seat 27 by e.g. being pressed into the seat 27.
  • Figure 4 shows a cross-section through the bushing 21 and the washer 23 of Figure 3 along the line IV-IV.
  • the washer 23 has a central opening 29 for receiving the screw 15.
  • the washer further comprises resilient members, illustrated as three flaps 31, the function of which will be explained below. Although three resilient members 31 are shown in Figure 4 , one, two, four, five or more resilient members may be used. Alternatively, a rim at least partially enclosing the diameter of the opening 29 and provided with one or more slits or slots may be used.
  • the resilient members 31 are used to define an inner diameter d w of the opening 29.
  • the inner diameter d w of the opening 29 is defined as the distance along a line going from the innermost portion of a resilient member 31 through the centre of the opening 29 to the rim of the opening 29 opposite to the innermost portion of the resilient member 31.
  • the inner diameter d w of the opening 29 approximately coincides with the diameter d r of the main portion 26 of the through-going axial bore 25. Even if this provides an appropriate size of the inner diameter d w , it is also possible that the two diameters, d r of the receptacle and d w of the inner diameter of the washer 23, differ from each other.
  • Figure 4 illustrates the resilient members 31 being in a first position. No force is applied to them.
  • the screw 15 is provided with a thread 33.
  • the screw 15 has an outer diameter d o defined by the ridges 34 of the thread 33 and an inner diameter d i defined by the grooves 35 of the thread 33.
  • the inner diameter is less than the outer diameter, d i ⁇ d o .
  • the screw 15 is thread-cutting, such that it can cut its way through the main portion 26 of the bushing 21, as is the case for the first embodiment.
  • the bushing 21 could be provided with a thread as well, which matches that of the screw 15.
  • Figure 5 illustrates the situation after the screw 15 has been pushed through the washer 23 by an axial force.
  • the screw 15 will enter also if the force deviates from axial, as long as it has a component in the axial direction.
  • the axial force used to push the screw 15 through the opening 29 of the washer 23 is not especially high; to push the screw 15 by hand force is for example sufficient.
  • the resilient members 31 are bent out of the plane of the washer 23 by the thread 33 of the screw 15. The resilient members 31 are thus displaced from the first position shown in Figures 3-4 to a second position allowing the screw 15 to pass through the opening 29, which temporarily has a larger diameter, since the resilient members 31 are bent inwards in the direction of the axial force.
  • the resilient members 31 When the pushing movement ceases, i.e. the axial force is not applied any more, the resilient members 31 will return to the first position. The resilient members 31 will then partly penetrate into a groove 35 of the thread 33, as seen in Figure 5 , such that the resilient member 31 retains the screw 15. The screw 15 will hence not move outwards again by itself, since it is retained by the resilient members 31.
  • the resiliency of the resilient members 31 is adapted such that when the screw 15 is used to hold an object, for example an inflatable curtain 3, the resilient members 31 are strong enough to retain the screw 15 including the weight of the inflatable curtain 3. However, it is yet possible to pull out the screw 15 again if applying a force above a predetermined level, e.g. if the inflatable curtain 3 is going to be exchanged. This predetermined level is selected to be high enough to ensure that under normal conditions the resilient members 31 are strong enough to retain the screw 15 including the weight of the inflatable curtain 3.
  • the screw 15 may be pushed until it reaches the main portion 26 of the through-going axial bore 25, which has a smaller diameter d r than the outer diameter d o of the screw 15. In order to move the screw 15 further inwards into the bore 25, it will be screwed.
  • the resilient members 31 will be able to retain the screw 15 as soon as the resilient members 31 are able to grip into a groove 35 of the thread 33. Hence the screw 15 needs not to be pushed as far as in Figure 5 . However, it is advantageous to push the screw 15 as far as possible before screwing starts.
  • the object to be attached in the example the inflatable curtain 3, is held in position at the object whereto it is to be attached, in this example the cantrail 5, by the screw 15 being retained by the washer 23, the person making the attachment will have both hands free to attach the screw 15 by screwing.
  • the screw 15 is preferably attached by a predefined torque which is selected to fulfil security standards.
  • the above-described attachment assembly 19 may be handled also for the case when the person making the attachment cannot see the screw 15.
  • the bushing may be dispensed with.
  • the washer is fixedly attached directly to the object to be attached to.
  • the method used to attach the screw 15 of the attachment assembly described above comprises the steps of:
  • the screw 15 When the screw 15 is pushed through the washer 23, it moves in the axial direction A. Even if it would be possible to combine the axial pushing of the screw 15 with a rotational movement, it is enough with only axial movement during the pushing. However, when the screw 15 is tightened to the first object, e.g. the cantrail 5, by screwing, the screw 15 performs a movement, which comprises rotational and axial movement. The combination of rotation and axial movement during screwing is influenced by the thread of the screw 15.
